If you are using Ruby stack for deploying your application, we strongly suggest to upgrade Rails to the latest version. We have released new versions of Ruby Stack native installers (all platforms), virtual machines and Amazon EC2 and Azure cloud images for the following platforms:

Ruby Stack 1.9.3, with Ruby 1.9.3-p484 and Rails 3.2.17

Ruby Stack 2.0.0, with Ruby 2.0.0-p353 and Rails 4.0.3

Ruby Stack 2.1.0, with Ruby 2.1.0 and Rails 4.0.3

Because one of the security issues affects PostgreSQL databases, we also released a new version of the Bitnami Discourse application which includes a fixed version or Rails.
